Metered billing is a pricing model commonly used in cloud services and cybersecurity solutions, where customers are charged based on their actual usage of resources or services rather than paying a fixed, flat fee. This model enables organizations to scale their costs according to their needs, paying only for what they consume, such as bandwidth, storage, or processing power. Metered billing offers flexibility and cost-efficiency, especially for businesses with fluctuating or unpredictable demand. In cybersecurity, this approach is often applied to services like threat detection, data analysis, or managed security, allowing companies to align their security spending with real-time requirements.
